feat(app): iOS-skallen — Capacitor, Xcode-projektet og et CI-job, der bygger den

Femte trin mod iOS-appen. Fladen fra trin 3 pakket ind i en rigtig app.

- `app/`: Capacitor 8 med SPM (ingen CocoaPods). `npm run sync` bygger web
  med VERDANDE_TARGET=app og kopierer det ind i Xcode-projektet; `npm run
  open` åbner det på en Mac. Bundle-id `dk.nolimit.verdande`.
- `app/ios/` er committet. Webbygget og den genererede konfiguration i det er
  ikke — sync lægger dem der.
- `NSAllowsLocalNetworking`: en hjemmeserver uden certifikat kan nås med http
  på det lokale net; alt på internettet skal stadig være https.
- Ikon og opstartsbillede tegnes fra web/static/icon.svg
  (scripts/generate-ios-assets.js). Kvadratisk og uden gennemsigtighed, fordi
  iOS runder hjørnerne selv.
- CI-jobbet "iOS app shell" bygger og synker på Linux og tjekker, at
  app-bygget ikke registrerer en service worker. Ingen Xcode i CI; det dækker
  alt op til den.
- docs/ios.md: hvordan appen adskiller sig fra en browser, hvordan den bygges,
  hvad der er ejerens skridt (Apple-konto, signering, TestFlight), og hvad der
  mangler — notifikationer via APNs venter på en beslutning om en relay.

+## Two editions: verdande and urd
+
+This repository builds one program with two faces. Start it with
+`VERDANDE_EDITION=notes` and it is **urd** — notes and nothing else: the task
+routes are not mounted, the sidebar has no way to them, and the program calls
+itself urd in its tab, its wordmark and its web manifest.
+
+Urðr is Verðandi's sister in Völuspá, and the poem has the Norns cutting marks into
+wood. Verdande is what is becoming; urd is what has become and was kept.
+
+Not a fork, because the two share everything that is hard — accounts, sharing,
+passkeys, the realtime socket, search, backups, migrations — and notes are about a
+twentieth of the Go here. A test walks both routers and fails in either direction,
+so "the task routes are not there" is measured rather than promised — 63 routes and
+five of nine MCP tools. See
+[Two editions](docs/editions.md).
+

 tested and what is not.

 - **Notes, beside the work.** Rich text that is Markdown underneath — headings,

+## The shape of all of it
+
+**The model proposes; you decide.** Nothing is written until you say yes, and the
+proposal is a line in the same syntax you type yourself — `Ring til Anders i morgen
+p1 #Firma` — sitting in a field you can edit before you accept it.
+
+That is not caution for its own sake. A model that edits your tasks directly has to
+be right *every* time to be worth having. One that suggests only has to be right
+often enough to save you some typing, and when it is wrong you have already seen it.
+
+It is also why the suggestion is a line rather than a set of fields: there is one
+reading of "i morgen" in this program, and a suggestion goes through the same
+[quick add](quick-add.md) parser as anything you type — including after you have
+edited it by hand.
+
+The model is given the names of the projects that exist and may name no others. A
+`#Projekt` it invented would create one by accident the first time you accepted it,
+and a guess must not be able to move a task somewhere you will not look for it.
+
 ## What it can do
 
-**Split a task into sub-tasks.** On any task: *Split with AI*. It suggests two to
-seven concrete actions and creates them as sub-tasks. Written in your language.
+**Tidy up the inbox.** In the Inbox, the menu → *Ryd op i indbakken*. For each loose
+line it suggests how you would have written it if you had finished it — project,
+date, priority — with one sentence on what it read out of the task. Accept, edit, or
+skip, one line at a time.
+
+**Find the tasks in a note.** Open a note → *Find opgaver i noten*. Only what
+somebody committed to or was asked to do; a heading is not a task and a topic that
+was discussed is not a task. Each suggestion quotes the words it came from, so a
+wrong one can be seen through rather than merely being wrong. The note itself is
+never edited — the task carries `[[the note's title]]` in its description instead.
+
+**Today's plan, in the morning.** **Settings → Beskeder → Dagens plan**, off by
+default; pick the hour yourself. One notification about what is due today and what
+has been missed, and what to start with — and the same text as a card at the top of
+**I dag**, where you are looking anyway when you start the day. The notification is
+the reminder; the card is where it stays.
+
+The card shows the plan *as it was sent*, with the time it was made, rather than a
+new one each time you look: a plan that says something different when you look at it
+than it said when it arrived is worse than either. **Forny planen** makes a new one
+when the day has moved, and it does not send a notification about something you are
+already looking at. With the morning notification off, the card offers to make one
+on the spot.
+
+The counts are done in the database and handed to the model as facts it may not
+recompute — a plan that says four tasks where there are three is worse than no plan.
+With no model configured the counts stand on their own, which is what you needed to
+know at seven in the morning anyway. Nothing due and nothing overdue sends nothing.
+
+**Mail that becomes a task you can act on.** Where a
+[mailbox](mailboxes.md) used to produce *"Anders Jensen: SV: SV: Vedr. levering uge
+12"*, the model writes the action the mail asks for — and leaves the mail alone if
+it asks for nothing. The subject stays in the description, so a mail it misread can
+still be read. If the model is unavailable the task is named sender and subject as
+before: a model that is down must not be able to stop the post.
+
+**Ask your own notes and tasks.** ⌘K, type the question, ⌘⏎. *"Hvad lovede jeg
+Anders i august?"* — search finds what contains the words, this answers the
+question, and the answer links to the notes and tasks it rests on. If nothing
+matches, it says so; a guess would be useless here, because you are asking precisely
+because you cannot remember.
+
+**Split a task into sub-tasks.** On any task: *Split with AI*. Two to seven concrete
+actions, created as sub-tasks.
 
 **A weekly summary.** A short note over what is outstanding: what looks urgent and
-what appears to be slipping. At most six lines — it is a prompt to think, not a
-report.

 ## What is sent
 
-Only what the feature needs: for a split, the task's title and notes; for a
-summary, the titles, dates and priorities of your open tasks. Never comments,
-attachments, or anything from a project the feature was not invoked on.

+# The install count

+verdande reports that it exists — and so does urd, which is the same program in
+its [notes edition](editions.md). Two values, once a day:
+
+```json
+{
+  "instance_id": "01a0806d-3601-7000-ad76-057f1f684881",
+  "version": "v0.44.1"
+}
+```
+
+That is the whole message. No IP is stored by the collector, no hostname, no
+domain, no account, no counts of anything you have made, nothing about what you
+use it for — and not which of the two editions is running, so the count does not
+tell the two apart either. The payload is small enough to be printed in full on the settings page,
+and it is printed there — a promise about telemetry is worth exactly as much as
+your ability to check it.
+
+## On by default, off in one click
+
+The alternative that was considered first was compulsory, and the argument against
+it is practical rather than principled: it cannot be enforced. The domain can be
+blocked, the binary can be patched, and a fork removes it in its first commit. So
+mandatory buys nothing over on-by-default while costing the trust the rest of this
+program works for.
+
+Which is why the first administrator to sign in is **told, unprompted**, with the
+real id, the real version and the real address in front of them, and two buttons.
+On by default is only defensible if it is said out loud without being asked; a
+settings page where it is stated fully is not the same thing, because that page is
+opened by people who already suspect there is something to read.
+
+**Settings → Data** afterwards: one switch. An explicit "off" survives upgrades.
+
+!!! note "This disagrees with the update check, on purpose"
+
+    `VERDANDE_UPDATE_CHECK` is off unless you ask for it, and its reasoning is that
+    a self-hosted app reaching out unbidden has broken the deal its operator made by
+    self-hosting. That is the same situation as this one, and the two defaults do
+    not agree. The case for treating them differently: the update check reveals an
+    instance to a third party (GitHub) and returns something you can act on, while
+    this returns nothing and goes to the project. Whether that is a distinction or
+    an excuse is a judgement call, and it was made deliberately.
+
+## What the collector cannot see, and what it can
+
+A request has a source address whether or not anybody writes it down. The collector
+stores none and logs none, and the code is arranged so the address never reaches a
+function that could — the table has nowhere to put one. But the request passes
+through a reverse proxy and a tunnel on the way, and those keep their own logs.
+"We send no IP" would be a half-truth; what is true is that nothing here records
+one.
+
+The ping is not authenticated either, so anybody can post a made-up id and inflate
+the count. That is an accepted trade: a token would have to ship inside every
+install anyway.
+
+## Running your own count
+
+Somebody running a fleet points **Settings → Data → Modtagerens adresse** at their
+own instance, and ticks **Denne instans er tælleren** there. Until that is ticked,
+`POST /api/v1/beacon` answers **404** rather than accepting quietly — an instance
+nobody made a collector must not become a bucket anyone can post into.
+
+The collector's page then shows totals, active in 7 and 30 days, and a breakdown by
+version. Publishing that number at `/api/v1/beacon/count` is a second, separate
+opt-in, and it has a floor under it (25 by default): a number that *falls* cannot be
+published as a fact — a bad release, a DNS change that quietly stops the pings, or
+lost rows all look like "fewer people use this now" — and a small number mostly says
+how little it takes to move it.
+
+## When it cannot reach
+
+The reason is written down and shown on the settings page. A beacon that cannot
+reach its collector otherwise fails in complete silence: it tries again tomorrow,
+the page says "last sent" with a date that quietly gets older, and nobody notices.

+# Two editions: verdande and urd
+
+One program, built once, with two faces.
+
+| | **verdande** | **urd** |
+|---|---|---|
+| What it is | Tasks, projects and notes | Notes |
+| `VERDANDE_EDITION` | `full` (the default) | `notes` |
+| Routes served | 200 | 137 |
+| Mark | ᚹ | ᚢ |
+
+Set `VERDANDE_EDITION=notes` and the instance is urd: the task routes are not
+mounted, the sidebar has no way to them, search answers with notes only, and the
+program calls itself urd in its tab, its wordmark and its web manifest.
+
+## Running the notes edition
+
+There is one image. The edition is an environment variable on the container:
+
+```
+docker run -e VERDANDE_EDITION=notes -v urd-data:/data -p 8080:8080 \
+    ghcr.io/kristianwind/verdande:latest
+```
+
+No second image and no rune of its own, deliberately.
+
+The edition is for an operator who wants an instance that genuinely has no task
+routes — the routes are absent from the router, not hidden in the interface. It is
+**not** how urd is normally reached. That is the second door, below.
+
+Two details that surprise people who look inside:
+
+- **The binary is called `/verdande`** and the database file is `verdande.db`, in
+  both editions. Not an oversight: it is the same binary, and renaming the file per
+  edition would be a migration hazard in exchange for nothing a user sees.
+- **The icons for both editions ship in the one image.** The server decides which
+  to serve at `/icon.svg`, because Safari looks for `apple-touch-icon.png` by name
+  and never reads the manifest, so renaming paths would have left iOS with the
+  wrong mark.
+
+## The second door: two apps, one instance
+
+urd is normally reached at **`/urd`** on an ordinary verdande. One instance, one
+database, one login, one set of links between notes and tasks — and two things you
+can install.
+
+| | verdande | urd |
+|---|---|---|
+| entry | `/` | `/urd` |
+| manifest | `/manifest.webmanifest` | `/urd.webmanifest` |
+| manifest `id` | `/` | `/urd` |
+| tab and mark | verdande, ᚹ | urd, ð |
+| database, account, login | the same | the same |
+
+An operating system does not install a URL, it installs a **manifest**, and the
+identity of an installed app is that manifest's `id`. Two manifests on one origin
+with different ids are two apps; two URLs sharing one manifest are one app with a
+bookmark. That is the whole mechanism.
+
+The shell is served per door rather than patched by JavaScript after the page
+loads, because iOS reads the page's `<head>` when somebody taps Add to Home Screen
+— and Safari looks for `apple-touch-icon` **by name**, having historically ignored
+the manifest's icons altogether.
+
+urd's manifest is built from verdande's rather than written beside it, so the
+fields the two genuinely share — the colours, the display mode, the language —
+come from one place and cannot drift. Six keys are changed: `id`, `start_url`,
+`scope`, the two names and the icons. An icon in the built manifest that urd has no
+file for stops the server rather than being passed through, because the symptom
+would otherwise be urd's install prompt quietly showing Verdande's mark.
+
+### The face is a preference, not a gate
+
+Entering at `/urd` makes that **window** wear urd's face: its mark, its name, its
+tab. It is kept strictly apart from the notes edition in the code, and the
+distinction is the one thing worth reading twice:
+
+| | what it means | what follows |
+|---|---|---|
+| `notesOnly` | the server has no task routes | a **guard** — the interface must not fetch them, they answer 404 |
+| `urdFace` | this window came in through the urd door | a **preference** — the routes are there, the data is yours, only the name differs |
+
+Conflate them and the urd face starts hiding data rather than chrome: a notebook
+would stop showing its tasks because somebody chose a different entrance. A test
+asserts the opposite directly — the urd window still gets 200 from
+`/api/v1/tasks`.
+
+The face lives in `sessionStorage`, not `localStorage`, and that is what lets the
+two apps be two apps: they share an origin, so they share localStorage, cookies and
+the service worker. `sessionStorage` is per window, and an installed PWA is its own
+window. It survives a reload, which it must — after the first navigation the
+address is `/noter` and nobody passes through `/urd` again.
+
+!!! note "One thing the two doors cannot have separately"
+    Theme, typeface and text size are shared, because they are in the localStorage
+    the origin shares. That was a deliberate choice: splitting them per face would
+    mean migrating everybody's stored settings for a difference few people want.
+
+## Moving between the two, measured
+
+A `/data` directory moves between the editions in **both directions, losslessly**.
+Same binary, same schema, same migrations — so this is not a feature that was built,
+it is a property that was checked:
+
+| step | result |
+|---|---|
+| verdande creates a notebook, a note in it, and a task | 1 note, 1 task |
+| the same directory, `VERDANDE_EDITION=notes` | `needs_setup: false` — same account. The note keeps its title, its body **and its `project_id`**. `/api/v1/tasks` → 404 |
+| the same directory, back to `full` | the task is still there; so is the note |
+
+The ownership stayed at the panel's service account through all three.
+
+So the way to move notes is to change the variable. `GET /export/notes.zip` is for
+getting notes **into other programs** — it writes one `.md` per note and carries the
+body and nothing else: no notebook, no sharing, no attachments, no pinned flag. That
+is the right division of labour, because the database already holds those.
+
+!!! note "The task rows stay"
+    An instance run as `notes` still has its tasks in the database; they are simply
+    not served. Harmless on a fresh instance, dead weight on a converted one — and
+    worth knowing before handing a converted instance to somebody else.
+
+## Why one codebase and not a fork
+
+The two share everything that is hard: accounts, sessions, passkeys, sharing,
+invitations, the realtime socket, search, the backup format, the migrations. Notes
+are about a twentieth of the Go in this repository and reference no task type;
+tasks reference no note type. A fork would have duplicated the other nineteen
+twentieths in order to separate the one — and then every security fix would have
+needed applying twice, by hand, forever.
+
+So the split is a configuration value read in one place, and the thing that keeps
+it honest is a test rather than a convention: `TestNotesEditionServesOnlyItsOwnRoutes`
+walks both routers, compares them against a written-down list of the 63 withheld
+routes, and fails in **both** directions — a route that appears in the notes
+edition and a route that stops being withheld are both a failure.
+
+## An unknown value refuses to start
+
+`VERDANDE_EDITION=note`, `Notes` and `none` are all rejected at startup, by name,
+rather than being treated as "not notes".
+
+The silent direction is the dangerous one here. An operator who sets up an instance
+for notes and mistypes the value would otherwise get every task route served on it,
+with no error anywhere and no way to tell from the outside.
+
+## What urd does not have
+
+The 63 withheld routes:
+
+| | what |
+|---|---|
+| 29 | tasks, sub-tasks, labels, saved filters, reminders, the upcoming and delegated views |
+| 8 | the CalDAV server — every route in it reads or writes a VTODO |
+| 1 | `/.well-known/caldav`, which is a claim that a CalDAV server is here |
+| 1 | the ICS calendar feed, plus 2 for the token it is reached with |
+| 4 | the task exports: `tasks.ics`, `projects.zip`, and a project's `.csv` and `.ics` |
+| 2 | the Todoist and CSV imports, which create tasks |
+| 4 | project templates — a template is a project plus sections plus tasks |
+| 5 | sections, which group tasks: `section_id` is a column on `tasks` and not on `notes` |
+| 6 | the AI task features: split, tidy the inbox, and the day's plan |
+| 1 | the inbox hook, which pushes a line of text in as a task |
+
+Plus five of the nine MCP tools — `search_tasks`, `create_task`, `update_task`,
+`complete_task` and `add_comment`. The endpoint is still there; the tool list is
+shorter. A tool a model can call is a surface, and one that answers "there are no
+tasks" is worse than one that does not exist: the model tries it, gets an empty
+answer, and tells the person there is nothing to do.
+
+Everything else is the same program:
+
+- accounts, invitations, passkeys and two-factor
+- projects — which in urd are what a note belongs to
+- per-note sharing with other people, independent of projects
+- search, over notes
+- export, of notes
+- the mail, calendar and MCP surfaces, minus their task routes and task tools
+- AI settings, `ask`, and the note actions
+
+!!! warning "Still being decided"
+    Four connectors are reachable in urd today and have not been settled either
+    way, because each has a plausible notes reading and withholding them would be
+    deciding what this product is rather than closing a hole: the mail-in address,
+    IMAP mailboxes, Gmail, and Google Calendar. They currently file what they
+    receive as **tasks**, so in urd they connect and then have nowhere to put
+    anything. The same applies to one handler rather than a route:
+    `POST /api/v1/ai/notes/{noteID}/actions/apply` creates tasks from a note.
+
+## The name
+
+Verðandi and Urðr are two of the three Norns in Völuspá, and the poem has them
+cutting marks into wood — the act of writing something down. Verdande is what is
+becoming; Urd is what has become and was kept.
+
+An instance started without the task routes is a different product to the person
+using it, so it says a different name. That name is read from the configuration in
+one place (`Config.ProductName`), which is why there is no build-time flag and no
+second frontend: the frontend is byte-identical in both editions, and the server
+renames the two files a browser reads before any JavaScript runs — the HTML shell's
+title and the web manifest.
+
+!!! note "The beacon counts them separately"
+    Both editions report the same two values once a day — instance id and version
+    — and nothing else; see [The install count](beacon.md). The edition is not in
+    the payload, so the count does not distinguish them.

+# The iOS app
+
+The iOS app is the web interface bundled into a native shell with
+[Capacitor](https://capacitorjs.com). It is not a second interface: the same
+Svelte build runs in both, and everything that differs between a browser and the
+app lives in `web/src/lib/platform.js`.
+
+It talks to **any** Verdande server. The first screen asks for the address, checks
+it with `/api/v1/ping`, and then signs in there.
+
+## How the app differs from a browser
+
+| | Browser | App |
+|---|---|---|
+| Where the interface comes from | the server | inside the app, `capacitor://localhost` |
+| Which server | the one it was loaded from | the one its owner typed in |
+| Session | httpOnly cookie | a session token, sent as `Authorization: Bearer` |
+| Live sync | WebSocket with the cookie | WebSocket opened with a one-use ticket (`POST /ws-ticket`) |
+| Pictures and downloads | plain `<img>` and links | fetched with the token and shown from a blob (`nativemedia.js`) |
+| Service worker, Web Push | yes | no — WKWebView has neither |
+| Passkeys | yes | not yet — a passkey is bound to the server's domain |
+| Creating the first account | yes | no — done in a browser, then sign in from the app |
+
+The server side of this is `client: "app"` on `/auth/login`, the
+`capacitor://localhost` CORS rule, and the ticket. All three are in
+`docs/openapi.yaml`.
+
+An app session slides: every use moves its end forward, up to
+`VERDANDE_APP_SESSION_TTL` (180 days) unused. It is listed under *Enheder* in
+settings with the name the app gave itself, and can be signed out from there.
+
+## Building
+
+Everything up to Xcode runs anywhere, and runs in CI (`iOS app shell`):
+
+```sh
+cd app
+npm ci
+npm run sync      # builds web with VERDANDE_TARGET=app, copies it into ios/
+```
+
+On a Mac with Xcode:
+
+```sh
+npm run open      # opens ios/App/App.xcodeproj
+```
+
+Choose a simulator and press Run. In the app, type the address of a Verdande —
+`http://localhost:8080` reaches a dev server on the same Mac from the simulator.
+
+Plain `http` is allowed to **local** addresses only (`NSAllowsLocalNetworking` in
+`Info.plist`), so a home server without a certificate works on the same network;
+anything on the internet has to be `https`.
+
+`app/ios/` is committed. The web build inside it (`App/App/public`) and the
+generated config are not — `npm run sync` puts them there.
+
+The icon and launch image come from `web/static/icon.svg`:
+
+```sh
+cd web && node scripts/generate-ios-assets.js
+```
+
+## Putting it on a phone
+
+These steps are the account owner's — they involve Apple's terms, a payment and
+signing keys.
+
+1. **Apple Developer Program** membership (99 USD a year) on the Apple ID that
+   should own the app.
+2. In Xcode → *Signing & Capabilities*: choose that team. The bundle id is
+   `dk.nolimit.verdande`; it can change until the first upload and never after.
+3. *Product → Archive*, then *Distribute App → TestFlight*.
+4. In App Store Connect, add testers to the TestFlight build.
+
+## Not yet
+
+- **Notifications.** Web Push does not exist in the app. Notifications on an
+  iPhone go through Apple's APNs, and the key that sends them is bound to the
+  app's bundle id — so it cannot live on every self-hosted server. That means a

+  would talk to. That is a new connection from other people's servers, and it
+  waits on a decision before it is built.

+# Opening links
+
+A link in a task or a note opens in whichever browser your system opens links in.
+**Settings → Links** can try to change that — and the honest description of what it
+does is *try*.
+
+## What a web page cannot do
+
+Two things, and they set the limits of this feature:
+
+- **It cannot see which browsers are installed.** The list is deliberately closed:
+  it would be a fingerprint, distinctive enough to follow somebody from site to
+  site.
+- **It cannot ask the system to use a particular one.** A link goes to the default
+  browser, and there is no API that says otherwise.
+
+The only handle that exists is the URL schemes browsers register for themselves —
+`firefox://open-url?url=…`, `googlechrome://…`, `microsoft-edge:…` — and there is no
+way to ask whether one exists. You can only try it.
+
+## So the setting is an attempt
+
+Pick Safari, Chrome, Firefox or Edge, or write your own scheme. When you click a
+link, that scheme is tried first; if nothing has happened within about half a
+second, the link opens the ordinary way.
+
+The fallback is the whole reason this is safe to turn on. Without it, a setting
+that works on your phone would leave links doing nothing on your desktop.
+
+In practice: **it works on a phone**, where browsers register these schemes, and
+**rarely on a Mac or a PC**, where Chrome and Firefox do not. Edge on Windows is
+the usual exception. There is a **Prøv det** button for exactly this reason — you
+cannot ask whether a scheme exists, so it is better to find out on example.dk than
+on a link you meant to follow.
+
+## Writing your own
+
+Three placeholders, because browsers disagree about the shape they want the address
+in:
+
+| | |
+| --- | --- |
+| `{url}` | The address as it is — `x-safari-https://example.dk` |
+| `{encoded}` | The address as a parameter value — `firefox://open-url?url=https%3A%2F%2F…` |
+| `{stripped}` | The address without the `https://` — `googlechrome://example.dk` |
+
+## It belongs to the machine, not the account
+
+The choice is kept in the browser you are sitting at, not on your account — the
+same rule the sidebar's width follows. `firefox://` works on the phone and does
+nothing on the Mac, so a choice that followed the account would be wrong in one of
+the two places every time.

 !!! tip "Keep the address to yourself"
     Treat it like a secret. If you publish it somewhere, rotate it.
+
+## Pushing from another program
+
+The address above needs a mail server. When what you want is a shortcut on your
+phone, a script, or any service that can call a URL, there is a second way in:
+**Settings → Integrationer → Skub fra andre programmer** gives you an address to
+POST a line of text to.

+```bash
+curl -X POST https://todo.example.dk/inbound/hook/<token> \
+  -H "Content-Type: text/plain" \
+  -d "Ring til Anders i morgen p1 #Firma"

+
+The body is read three ways, because those are the three you meet: plain text from
+a shortcut that just sends what was selected, JSON with a `text` field from a
+service, or a form field from a webhook form. The first line becomes the task and
+the rest sits underneath it, and the line goes through the [quick add](quick-add.md)
+parser — so "i morgen", "p1" and "#Firma" mean here what they mean in the box at the
+top of the app.
+
+**The address is a key.** It has its own token rather than sharing the mail one:
+the two are the same kind of secret but they leak separately, and a URL that has
+been sitting in a shortcut on a lost phone has to be replaceable without changing
+the address other people have in their address books. A token here can do one
+thing — put a task in your inbox — which is why it is not an
+[API token](api.md), which can do everything. Change it under the same setting; the
+old one stops working at once.
+
+**POST only.** A GET would be easier to call, and that is exactly the problem: a

 many, and a note in a project inherits every one of those answers.
 
+### Sharing one note with one person
+
+Filing a note in a project is the right tool when the note belongs with a body of
+work, and the wrong one when it is just *let Sofie see this*. **Del med personer**
+at the foot of the note does the second: this note, this person, as reader or
+editor. Only the note's owner can share it.
+
+Type an **email address** rather than picking a name, and one of two things
+happens. An address that already has an account is shared with straight away. One
+that does not gets an invitation — a link that creates the account and the share
+together, so the note is theirs the moment they sign up. Invitations wait in the
+panel under the note, where they can be withdrawn; that is the only way back, since
+only the token's hash is stored and a link sent to the wrong address cannot be
+looked up.
+
+### Naming somebody in a note
+
+Writing `@Sofie` in a note shares it with her and tells her. Naming somebody in a
+note *is* wanting them to read it, and doing it as two acts — write the name, then
+open the panel and find the person — meant the second was forgotten, and the note
+sat there addressing somebody who could not see it. The editor suggests names after
+`@`, the same way `#` suggests projects.
+
+- **Only the owner's mentions share.** An editor may write the name; giving
+  somebody else's note away is the owner's alone.
+- **As a reader**, which is the least that satisfies "look at this". A role you
+  have raised in the panel is never lowered by a mention.
+- **Only a name that has just appeared** counts. A note is saved on every typing
+  pause, so without that every save would be another share and another notification
+  about the same name.

+Two places to search from, and they now agree. The field above the list filters it
+in place. **⌘K** searches everything at once — tasks, projects, notes and the
+settings — and picking a note from it opens that note *with the rest of the matches

+other results existed only in the popup you had just closed. The address carries

 ## Putting notes away

+# Notifications
+
+What other people did that you need to know about, and what the day has in it.
+Verdande tells you in three places at once, and they are the same thing said three
+ways: the **bell** in the header, a **push** to your devices, and the **badge** on
+the app's icon.
+
+## What causes one
+
+| | |
+| --- | --- |
+| Somebody edited a note shared with you | Repeat edits fold into one line while it is unread |
+| Somebody shared a note with you | Once, when it happens |
+| Somebody shared a project with you | Once, when it happens — the entry opens the project, and its share panel has a *Leave the project* button |
+| Somebody named you in a note with `@` | Instead of "edited a note" — one act, one message |
+| Somebody gave you a task | Only on the change, and only to the person who got it |
+| Somebody commented | |
+| [Today's plan](ai.md), if you turned it on | In the morning, at the hour you chose — it opens the card on **I dag** |
+| A new version is out | Administrators only, once per version |
+
+Not your own actions: the server does not tell anybody what they just did
+themselves. And not everything that happens — a bell that rings at every change in
+a shared project is a bell people stop looking at.
+
+**Repeat edits are folded.** A note is saved on every typing pause, so one person
+writing for five minutes would otherwise be twenty identical lines. While the
+message is unread, a further edit moves it back to the top and says who touched it
+last. Once you have read it, the next edit is a new thing to be told.
+
+## Push, and the badge
+
+**Settings → Beskeder** turns on Web Push for the device you are sitting at, per
+device: the phone in your pocket and the laptop you have open are different
+answers, and a permission granted on one is not the other's.
+
+The **badge** — the number on the icon in the Dock on a Mac, on the taskbar on a
+PC — needs the app to be installed (added to the Dock, or installed as an app in
+Chrome or Edge). Half the point of being told is being told while you are doing
+something else, and the icon is the only place the app can say anything then. It
+counts unread messages and goes down by itself as you read them. Firefox does not
+support it; nothing else changes there.
+
+The sentence you see is written in your browser from *what happened* and *who did
+it*, so an English interface gets an English bell. The server's own wording is
+Danish and is used only for push, which has no dictionary to look a phrase up in.
+
+## Telling you about a new version
+
+If the [update check](configuration.md) is on, administrators get one notification
+per version — never one a day about the same one — and it leads to
+**Settings → Beskeder**, where the button that restarts the instance to update it
+sits. With the check off, nothing is fetched and nothing is said.

+        Reminders have always had to be set one at a time: a task written as
+        "i morgen kl 9" got a time and no alarm, because nothing creates a reminder
+        by itself. That is the right default for a task with no clock — there is no
+        moment to ring at — and an errand you walk every time for a task with one.
+
+        `minutes` is relative to the due moment and **negative for before it**, the

+        due moment. `null` turns the default off, which is where every account
+        starts — switching it on for everybody in a migration would have meant
+        alarms nobody asked for, on tasks already lying there.
+
+        A positive number is refused. An alarm after the thing it is warning about
+        is not a reminder, and accepting one here would make the single mistake this
+        value can make — a sign the wrong way round — look like a choice.
+
+        The default never stacks on an alarm the task already has, and a task can

 anywhere: the first person to open a fresh instance creates the administrator
 account, and after that people arrive by invite link.
 
+## Being let into a project
+
+Two different situations, one panel — **the project's ⋯ menu → Share**.
+
+Somebody who **already has an account here** you pick from a list by name. You do
+not need to know their email address to share a project with a colleague whose
+name you know. The accounts on an instance are a closed set — there is no open
+signup, every one of them was invited — so listing them to each other is the
+address book the feature needs, not a disclosure.
+
+Somebody who is **not here yet** you invite by email. If the address turns out to
+belong to an account it becomes an ordinary share straight away; otherwise it
+becomes a link that creates their account and their membership at once. With no
+mail server configured the link is shown in the panel instead of being sent, which
+is the correct behaviour on a one-person instance rather than an error.
+
+**You are told, and you can leave.** Being added to a project is not something
+that happens to you quietly: the bell says who shared what, and the entry takes
+you to the project. In the share panel, anybody who is not the owner has a *Leave
+the project* button. That is deliberate rather than an approval step — an
+invitation waiting on a yes means the person who shared thinks it is done while
+the work sits still. What was wrong was the other three-quarters of it: you were
+added without being asked, without being told, and with no way out except asking
+the owner. The owner cannot leave their own project; that is a transfer of
+ownership, and there is no transfer yet.
+
+An invitation that has not been taken up stays listed under the members, greyed,
+with a × to withdraw it. Without that it is invisible — the person has no account,
+so they are neither a member nor somebody you can pick — and the usual next move
+is to send it a second time. The second link works exactly as well as the first,
+and then there are two to keep track of.
